The trunk line network of utilization [ Japan-domestic services the area along a roadway line of the expressway of the [ Inland area as the public works project.

On the occasion of Niigata Tsuetu Earthquake(VŠƒŒ§’†‰z’nk), it considered the fragility ( the stop of the nuclear reactor of Tokyo Electric Power in Niigata Prefecture Kashiwazaki (VŠƒŒ§”è) ) of the supply system of the electric power energy and this Institute contributed this article.

As for it, unexpectedly, when the Eastern Japan Great Earthquake ( March, 2011 ) this time occurred, too, the nuclear power plant of Tokyo Electric Power and 1st of Fukushima (•Ÿ“‡‘æˆêŒ´”­) fell into the abeyance of being suffered and the management likewise. By this thing, Tokyo Electric Power jurisdiction in the metropolitan area caused power supply lack in the summertime.

By introducing this article below, it feels happy if becoming the some help of the earthquake disaster reconstruction this time.

á Submission of the Issue â

It was a crude gas supply project from Russian Sakhalin to being waiting, the country which lacks of, but it came here and one barrier lay ahead.

As for the transportation by the LNG ( the Liquefied Natural Gas ) method, by "Sakhalin II ", the acceptance of the electric power and the gas company of the demand side, too, was decided and it was in prospect somehow of it.

As for left "Sakhalin I ", for now, in the marine construction method by the pipeline, the plan is proceeded with by the mind but easily, the plan doesn't develop.

As the big factor, it is in Japan on the earthquake archipelago and being the conception to have avoided so far in the country to construct a pipeline along the Pacific coast in Hokkaidou(–kŠC“¹) , the northeast and Kanto (ŠÖ“Œ) area with the earthquake frequencies which are many remarkably in it is given first. Also, the marine route gets to bring about compensation for fishing industry negotiation with long-range crossing, too.

Therefore, aren't you putting on the time to consider the Inland area, the method ( the reference: these columns " the web of expressways in the eastern Japan and the Hokkaidou area " ) which underlays a gas pipeline specifically along the area along a roadway line at the expressway in the country, too, in the future as the route plan which replaces it?

áDefinite plan| Outlineâ

Even if it tries to execute this " Inland area " plan specifically suddenly, there is not yet easily so. Regal restriction is set up in the entanglement about above all, too. It is the easy thing that disentangles this one by one.

This place has no choice but to wait for the decision of the administration side. However, there is a section where a gas pipe line is already constructed by good fortune in the considerable distance in the country, too.

It is, among " Sapporo(ŽD–y) - Yufutsu(—E•¥)" and so on among " Niigata(VŠƒ) - Tokyo (“Œ‹ž) " or among " Sendai(å‘ä) - Niigata(VŠƒ) " ( The reference: These columns " the gas pipeline network in the eastern Japan area " ).
.


y Primary Route z

First, it is the one which utilizes the existing pipeline which exists as the First Stage floor.

It is specificF

‡@ Hokkaido (–kŠC“¹) Route

Public welfare around the area of the neighborhood of Sapporo(ŽD–y) -city and Tomakomai city (“Ϗ¬–q) and Chitose(çÎ) city and the gas pipeline ( the 75 km full length, the diameter are 35 cm ) to make industrial are formed in the natural gas which is produced from the Yufutsu(—E•¥) oil gas rice paddy at present by Hokkaido.

‡A Sendai (å‘ä)- Niigata(VŠƒ) Route

This line ( the 261 km full length, the 50 cm diameter ) is supplied to the public welfare around Sendai city and being industrial and so on at present.

(As for above-mentioned 2 routes, it refers to Japan Petroleum Exploration Co., Ltd. Corporation's home page " the supply network " ).

‡B Niigata(VŠƒ) - Tokyo(“Œ‹ž) Route

As for this line, it refers to INPEX CORP. Teikoku Oil Co., Ltd. Corporation's home page " it opens natural gas " pipeline mapping ".

It begins the gas pipeline of these existence above [[ because it cooperates successfully. However, actually, it depends on the size with the diameter of the main line pipeline from Sakhalin, too,: one line seems to become already need concurrently with these existence lines probably.


á Construction Route â

Then, it is a specific construction route but the characteristic of the construction route in this place is avoiding " the Marine Route " to the utmost.

Generally, as for the damage such as the damaging of a building to the earthquake, the " basement " part is slighter than " the ground troops " ( It becomes the one where depthk equal to or more than 1 - 1.5 m of the basement lof laying underground, too, is fair if both the pipeline of this type becomes economically ).

Also, it often generates the epicenter of the earthquake, too, in the Sanriku-offshore fitting(ŽO—¤‰«) and the one which lays a pipeline underground to the inland area is safer ( The reference: These columns " the earthquake-risk distribution status ", “Œ‹ž‘åŠwo”ʼnï).

Moreover, when a pipeline is temporarily suffered, the Inland area is easy to repair. Also, a valve station is established every 10-15 km and in case of accsident, the measure which blocks off gas surely is caught.

After that, it constructs a Marine pipe line and it Inlands at the northern most tip on the side of Honshuu (–{B=mainland ofJapan) and in Shimokita(‰º–k)-peninsula on it in Tsugaru(’ÃŒy)-strait, via the existing road, it goes south and it leads to " Sendai (å‘ä)" in it and Touhoku (“Œ–k)roadway from " Hachinohe (”ªŒË)" ( Incidentally, as for among ) of ( " Sendai - Niigata ", in the present situation, because it is catching the form to convey the natural gas which is produced in the Niigata prefecture to Sendai with the pipeline, the above ) of ( pipeline k the 40 inch caliber = 102 cm l which is new becomes necessary ).

It connects with above-mentioned existence pipeline from here. This place becomes a route in the First Stage floor.

As the Second-Stage, it connects Touhoku roadway with the trunk line gas pipeline network in Tokyo Gas jurisdiction which is underlaid in the Saitama(é‹Ê) prefecture more after that from " Sendai ", leading to " Fukushima " - " Kooriyama (ŒSŽR)", going south.But, this conception is one as the next best thing plan and is not a conception in the above form.

Therefore, there is a pipeline which can have led to Sendai the neighborhood or doing the becoming of the Liquefied Natural Gas ( LNG ) to have established several power plants of the live natural gas burning a little more in the place of the metropolitan area coming ( Fukushima and Kooriyama and so on ) by which or for it to have used existing plant and so on and actually, it must cater for the demand of gas.

Incidentally, as the way of underlaying a pipeline at the expressway, as for that ‡@ is general, as for the ‡A tunnel part which installs bound earth and a fill part in the excavation or the ground and so on, as for the crossing a mountain, necessary ‡B River Department digs many of riverbeds and [[ so on which prevents damage to the pipeline by the landslide is thought of by the case of ‡C which excavates a shoulder of the road part.

áThe advantage of the Inland Constructionâ

If introducing the Primary advantage of underlaying a pipeline in the Inland area to the above, too, but seeing it from the side of the enterprising body(contractor) in the other:

@‡@ A fishery compensation duty is reduced.

@‡A It becomes independent construction if being a Marine pipeline, but more than one business unit is related if being an Inland area and it is possible to attempt for the total operating expenses to reduce.

@Also, it is:

@‡@ The local goverment gains the fixation income, by the fixed asset tax which depends on the construction of the pipe line and roadway in the local government and so on

@‡A Also, Privatized Japan Highway Public Corp. gains the fixation income in the name of the construction rental charge of the pipeline and so on.

@‡B If above all, too, is a inland route, in the area along a line of the pipeline construction, directly, it is possible for the pipeline to connect and it is possible to attempt the public welfare and and so on industrial large-scale gas demand.

It is possible to attempt a profit to both of the person concerned such as the above mentions.


¦ If there is a fiscal resource which provides a fund by the 100 billions yen scale to the pipe line underlaying by the petroleum in the far country not to find whether or not it is, servicing a gas pipeline network in its own country will be the first.
